The Texas Department of Transportation plans to temporarily close the two right main lanes of US-75 to allow for work on the Galatyn Parkway extension. The closures will occur 9 p.m.-5 a.m. beginning Tuesday, Wednesday and Thursday nights.

The extension of the Galatyn Parkway overpass is funded in part through Richardson’s 2010 Bond Program. Construction of the project is expected to be complete this month.
